Vessel-wall images of femoropopliteal artery and vein of a healthy 26 year-old subject. Forty contiguous slices are shown in superior to inferior direction (left to right from the top left panel) direction. Larger transmural pressure of artery maintains circular cross section throughout the slices distinguishing artery from adjacent vein. We note that the blood signal suppression level is the same in artery and vein even though the velocity waveforms are quite different.
